What is the most insane, cruel thing the Joker ever did in the Batman comic books?

This question is geared more toward those who know the story and comics very well from years ago to today. Think of the craziest cruelest thing the Joker has ever done.

I would say the constant torturing of not Batman but Jim. First he cripples and raping Barbara and then he kills Sarah while she is trying to save all those babies... I don't think anyone would have blinked if Jim would have put the bullet in his head rather than his knee.

After restraining Batman, forced him to wear that dreadful face paint.

i remember him (jack nicholson in the movie) "toasting" one of the lead members in his "clan" just for fun with a hand-shake buzzer. afterwards the guy just looked like a skeleton...

that was random and pretty cruel

Well he shot and paralyzed Barbra Gordon, and tried to make her dad commissioner Gordon crazy by showing him nude pictures of her lying on the ground shot. Then there was the time when he killed the second Robin with a tire iron.

He killed the 2nd Robin, Jason Todd

i would say crippling barbra gordan (the original batgirl) then forcing her father (commissioner gordan) to watch a video of the joker vicomizing his daughter.

it was not said but it was highly incinuated that the joker raped batgirl and forced her fatehr to watch. this hasn't been confirmed but if you read the issue, its pretty obvious that is what they were trying to show.

If you ever get the chance watch the unedited/ unrated version of Batman Beyond: Return of the Joker animated movie.

One of the best Batman vs. Joker stories ever.

Killed the first, original, Robin. The ones you see in the comics today (if there still is one) is probably the 3rd

Killed his parents.
